According to Bulbapedia, there are 559 moves in the game. Smeargle can sketch all but struggle and chatter. He also probably wouldn't carry sketch for a battle, so I won't count that. That leaves 556 moves total for him to learn. nCr=n!/(r!(n-r)!). n=556 and r=4, making 3,939,049,415 possible combinations for a smeargle moveset.

Spore makes them go to sleep. Quiver-dance and Bulk-up are boosts to pass and when combined they boost all your basic stats(Accuracy and evasiveness being secondary stats). Baton-pass passes the stat boosts.

So basically, Smeargle prevents fainting from Focus Sash, and spores them to sleep if she doesn't attack first. Either way, asleep. This gives her a chance to set up, Stealth Rocks, possibly a few layers of Spikes, and some Toxic Spikes to get that in-between damage rolling. Lets just hope, as the user, you can get set up quickly. And man, does this thing screw you if you don't have a rapid spinner. ;P

False Swipe gets a STAB+Technician boost and leaves one HP for the Pokemon you're trying to catch. Spore leaves them with sleep status, which is optimal for capture. Heal block is for legendary Pokemon that like to restore their health, and soak can turn your opponent into water type, meaning that ghosts that would otherwise be immune to false swipe no longer have that luxury. Not only does soak eliminate their STAB in most cases, but it lets you use net balls on them if you can't use dusk balls. (that one is more situational, but it can still be helpful depending on what verison you own.) Mean Look prevents manual fleeing, and since the Pokemon is asleep, it has a low chance of being able to get in a roar on you.

I remember in HeartGold SoulSilver and in Pokemon X and Y sucuine entei rakiou articuno zapdos and moltres leave (in X and Y articuno zapdos and moltres disappears until you see then about 9 times) in HeartGold and SoulSliver you have one turn. But for other pokemon with roar its Great !

Well a good moveset would have lock on and a one hit k-o move like sheer cold then moves like earthquake and psychic to defend against fighting types. Sheer cold is better becuase it effects all types.

Shell Smashing Smeargle
@Focus Sash252hp 4Def 252SpeedJolly/Timid nature-Spore
-Baton Pass
-Shell Smash
-Destiny BondI had allot of fun with this set yesterday, considering your reading this on the 30th of may.
Ok so the only type of smeargle you see in the current meta game is Spore.Baton Pass.Shell Smash, No one ever thinks about the last move.
So why not destiny bond.
So heres the strat- Send out smeargle first use shell smash (yes first, unlike other sets that allows you to out speed your opponent to put them to sleep, that then allows you to spore so they wont wake up and kill the pokemon passed to which if you use spore first they would have a good chance, though dont use if the pokemon is well known for a priority move which most leads are not.)Second spore then pass.
Sweeper sweeps.
Ok sweeper eventually gets taken out so switch back in 276 speed will out run most pokemon so you can then spore them and use the usual tactic pass again.
But If the foe is sweeping your team and it will loose you the match send in 1hp smeargle with destiny bond, who will expect that, now you have no major threat to deal with.

Start off with Shell Smash, if you go down to your focus sash then, put them to sleep with added speed. Endeavor them to 1hp too, then out speed them with ExtremeSpeed or Mach Punch. If they don't hit you first go, do another shell smash and up your attack!

First, go for either Agility or Belly Drum (use Belly Drum ONLY if your opponent's Pokemon can't one-hit the smeargle). If you use Belly Drum, follow up with Protect to regain some of the lost HP with Leftovers. After that, use Baton Pass to give the boost to either a speedy poke or a physical poke.

Used correctly, this can make any physical attacker with decent speed impossible to touch.
It should be taken note of that it would help lots to also have a priority attack on whoever you are Baton Passing to, because if you pass to, say, Salamence, an Ice Shard might almost kill it. So be aware.

Soak is for turning the opponent into a Water type and use Thunder on him. Bullet Punch is for Priority but Charge Beam can be used on the Water type, being super-effective and having a chance to raise Smeargle's low Special attack. Hurricane is also a good move in Rain.

-Lunar Dance for healing completely wounded Pokemon on your teams on Wi-Fi battles/Normal trainer battles and for healing their PP.Smeargle will faint using this move so use it later when a teamate is low on Hp/PP.

-Quiver Dance for raising speed/special attack/special defence.

-Calm Mind for raising attack/special attack.

-Batton pass for passing the states to the next Pokemon.

Hope this is a great moveset with smeargle if you don't like Calm Mind replace it with a better state raising move.

First turn spore, then stealth rock and spikes, if you get spore with focus sash intact you can spore again, maybe maxing out spikes at three, then toxic spikes or seismic toss, your preference to either dent the lead or get more entry hazards up, seismic toss keeps him from being immobilized by taunt.

Love this! I was also thinking of creating a whole team of Smeargles since I got a box and a half with 2-3 IV Technician/Own Tempo Jolly Smeargles from breeding my main one...
You've come up with a great idea and I might just adapt to this. :)

So here's the objective of this set: when you use Spore on your opponent, you can use Taunt(optional). Right after you Taunt your opponent make sure you use Imprison. After that use transform. Your opponent will now be struggling to take out your Smeargle
